    In a study of 420,037 cell phone users, 161 subjects developed brain cancer. Test the claim that cell phone users develop brain cancer at a rate that is different from the rate of 0.0340% for people who do not use cell phones. Because this issue has such great importance, use a 0.005 significance level. Use this information to answer the following questions. a. Which of the following is the hypothesis test to be conducted?

    In a study of 258,001 cell phone​ users, it was found that 43 developed cancer of the brain or nervous system. Assuming that cell phones have no​ effect, there is a 0.000234 probability of a person developing cancer of the brain or nervous system. We therefore expect about 61 cases of such cancer in a group of 258001 people. Estimate the probability of 43 or fewer cases of such cancer in a group of 258,001 people. What do these results...
